dc.description.abstractIn the paper the problem of the real-time emission control is discussed, where the air quality forecast is based on the regional-scale model of air pollution transport. The problem formulation utilizes the optimal control technique for distributed parameter systems, which is integrated with the governing equations of air pollution dispersion process. The approach presented in the paper is sulfur-oriented and a dynamic model of sulphur oxides transport is the main forecasting tool used in the optimization algorithm. The control problem is formulated as on-line minimization of an environmental cost function, by the respective modification of emission level in the controlled emission sources, according to the changing meteorological conditions. A set of point-wise emission sources (power plants) with known location and emission characteristics is considered as the controlled object. The minimized objective function includes the air quality damage, as well as the cost of the controlling action. The emission control process is based on a gradient optimization algorithm. The back-trajectory technique (based on the adjoint equation solution) is used to calculate the gradient of the objective function in the main optimization procedure. The test computations have been performed for the set of the major power plants in the selected industrial region of Poland, and some determined meteorological episodes.de
